To all whom tmay concern:

Be #it known that we, JOHN KosU'rz and JOHN BUNTA, subjects of the King of Hungary, residing at'Akron, in the county of Summit and State of Ohio, have invented certain new and useful lmprovements in Tire-Unwrapping Machines, of which the following is a specication. l

This invention relates to certain new and useful improvements in' tire unwrapping machines. y y l It is well understood in the art of tire manufacturing that in the formation of tire casings or shoes formed of rubber that the rubber is formed \or molded into proper shape upon the fabric carcass and is then completely enveloped in a fabric winding preparatory'to vulcanization.

The primary object of the present invention is to provide a machine for the expe: ditious removal of such winding from the completedl tire afterbeing vulcanized," the winding fabric being deposited 'upon ready for re-use. 1 `While the present invention' is primarily adaptedfor removing such fabric windings from a tire, the same is readily adaptable for wrapping a tire by" winding the fabric therearound, such, operation being accomplished byna substantial vreversal of .the aforementioned unwinding operation.

During either the wrapping lor vunwrapping, of the strip of material orI fabric proper, provisionis made 4for holding the spools Afabric taut to insure smoothness in operation while means are provided operable si-l multaneously with the machine lfor bodily shifting the tire -into proper position for being operated upon. l 40 j. A further object is to provide such a des.

vice adapted to receive and revolve an automobile tire while a covering strip 'thereon is simultaneously unwrapped in a taut condition and deposited upon a receiving spool.

It will be understood that the device may be employed for wrapping and unwrapping other `objects than tires Vand whether the same are circularor elongated -in form and that also the device vmay be employed Vfor wrapping a paper covering around the tire after its `completion lpreparatory to Shipping or storing the same.

'l With these general objects in lview and others that will appear as the nature of the invention isbetter understood, the same consiste in the .novel COIlStruction, combination and the-operating means therefor.

and arrangement of parts hereinafter more.

Fig. 14 is an enlarged side elevation of a portion of the Vrack and shuttle showing the strip an'd shuttle guides. Fig. 15 is a transverse sectional view taken upon4 line XV-XV ofv Fig. 14, and, Fig. 16 is a detail view partly in elevation and partlyA in section and illustrating a modified" form of the spool operating means. j

-In referring to the drawings, it will be noted that the device is illustrated in its operation asfan unwinding device for .tire

wrappings and the same broadly consists of .a mounting table 4'10 provided' with the mechanism hereinafter described for removing the fabric strip or tape 11 from the rub' ber tire shoe 12 by unwr'apping the same therefrom, it being noted that the direction of movement of the tire and *the tape as well uas the shuttle 18 and its drive member 14 are illustrated by arrows in the side elevational views, Figs. 1 and 2 of the drawings. A circular bracket 15 shownl in the preferred construction in the form of a rack 'is adjustably mounted upon the table 10 by having a radially-extending .arm `16- of 'the bracket journaled upon ak rod 17 carrled by 55 l A take-up roller 35 is shiftably mounted in opposite frames 18 and 1.7.8 mounted respectively upon the right hand and left hand l sides of the top 19'of thesaid table. A per-` forated block 2O is journaled throughth'e 5 bgacket arm 16 rearwardly of the rod `17 'and'a position.;` Oppositelugs24 areprbvid'ed at 'l the forward edge of the=tableftop-`191fo the reception of the fbracket=-1-5 therebetween vwhile a receiving-.notch 25'1 is "alsojprovided -in theforward edge of thehtableftop for a- 'commodating the movements of rthe bracket 'and' a `y set-screw' '26 is carried-,byone offth'e-A lugsz24 for'engagingthe bracket and mainvtaining'fthe samefin its 'desired lowered Vposition and coperating with the bolt 'and-nut means heretofore described in maintaining the bracket operatively arranged'- Bypi'votallymounting the bracket armlfon'the rod.

i 17 the circular-rack portion '15jof I thebracket may-bemeadily adjusted to cause the tire 12 tovpass ydirectly through the central axis thereof,` and thereby cause the tape 11 to remain taut at all times. The necessity of pivotally mounting the .bracket-will atfonce be understood as tires, of different-sizes `would otherwise passvthrough the bracket at points 'olf center thereof. l j I l .The shuttle 13 is in the form of-a-.rng'or annulus mounted for 'revolution withinthre grooves vofftwo forwardly and two rearwardly"arranged groovedv pu1leys27. and 28 respectively carried by the bracket l5, the

shuttle beingthus mounted in a plane paral-v lel tothe rack 15 and concentric with the central circular opening 29'ther'eof,.it being seen that the bracket 15A is provided with a toothed surface 30 upon the .inner edge thereof adjacent the saidshuttle 13.A lA power shaft -31 is journaled in opposite brackets 32 at the rear of the frames^18,l87 and is. vadapted. for loperation from any source of power supply not shown. The aforementioned driving member v14 is secured to the power shaft 31 and-received an endlessbelt 33 passing thereover and thence. over the rear ,pulleys 28 and in fric.- tional engagement with the periphery 34 of the shuttle 13 between the said pulleys 28.

Upon turning the power shaft. 31 .in the desired direction, the drivemember 14 willbe operated frmoving the belt .33 in engagement' with the shuttle 13, thereby .'.revolving the bobbin relatively of the'fbracket V15, it beings'een that therrequired frictionaltensionis main'- upon a` clutch collar 44 journalediiponthe tained upon thev belt 33 by retaining the i bracket at the desired 4adjustment byimeans of the-screw 26 and-nut 23, althoughif de- Two drums 37 -and'38 are arranged for `mounting and turning the tire' 12, the's'aid drums being secured upon the forward ends of shafts 39 and 40 respectively, which are journaled in parallelism' to-'the opposite 75 frames 18 and l18 respectively of thetable jtop l19,lth,e shaft' 404 and drum- 38 being-positioned Ain a plane 'slightlylhigher than the -shaft 39 and drum 37, the saiddrums being provided with plain curved grooved surfaces for receiving the vtire12 thereon as best yillustrated in Figs lrlan'dl 2v ofthe-drawings The upper shaft-40is rendered vertically ad- '.,justable upon its mounting frame 18 by means of adjustable blocks 41, whereby the drums 37 and 38 may be inwardly positioned 'to lcause a '-tire to -pass centrally thereth'rough. After continued operation of the 'machine, thebracket A15,l iscausedY to sag -or slightlymove Idow-nwardly by- Cown 'weight, andthe strain upon-the'winding tape., Instead-"of readjusting the drums, the

A cord 48 is attached to the lower end ofthe clutch lever 46 and is connected to a foot pedal 49 whereby the lever 46 may be swung with its upper operi ating vend 50' outwardly positionedV and vwith 1 10 the clutch sleeve 45 entirely disengaged from the clutch collar 44, `in* which position the shaft 3 9 will remain at rest uninfluenced by the continuous operation o f the clutch'co'llar The Shafts 39 and 40 are each provided 'with a sprocket wheel 51 over which a sprocket chain 52 is'maintained so that the turning of the. lower shaft 39 by the power shaft 31 in the manner heretoforeset forth., simultaneously turns the upper'shaft-40 at the same speed and in the'same directionso that'the drums 37 and 38 will be operated for slowly revolving the tire 12 in the direction lindicated by the arrows in Figs 1 and 2 of the drawingsvand the turning of 125 the drive member 14 and the shuttle 13 in the .directions also therein shown. A spin- Vdle 53 is journaled transversely through the shuttle 13 1and is restrained against longipositioned collars 54`carnied by the -vsaid l i tively to the bracket 15. The said flexible spindle. A pinion 55 is journaled upon the spindle 53 in4 mesh with `the rack teeth 30. A flexible connection is ,provided between the pinion 55 and spindle 53 whereby a slipupon the spindle 53 whenever said spindle is restrained fromV rotation, it being understood that the pinion 55 mustnecessarily rotate whenever the shuttle 13 is turned relaconnectionI abovel referred t6 is here shown in the form of two disks 56 arranged at opposite sides of the pinion 55 and splined to the spindle 53 sopas necessarily to revolve therewith, intervening packing rings 57 being arranged between the disks and the said pinion, ,An expansion spring 58 is arranged encircling the spindle 53 and bearing between the inner disk 56 and the adjacent Spindle collar 54 `while a set screw 59 is screw-threaded in the end of the spindle 53 and is adapted to force a terminal washer 60 carried by the end of the spindle into frictional contact with` the adjacent disk 56',

`thus compressing the spring 58 and giving the desired firmness to the connection betweenthepinion 55 and spindle 53. A spool 61 is removably mounted upon the end62 of the spindle 53 at the opposite side of the shuttle from the pinion 55 and is removably maintained thereon by means of spring ngers 63 carried by the said spindle end and adapted to engage withinnotches 64 of the said spool ,61, it'being understood that by compressing the iinger 63, the spool 61 may be readily removed from the spindle.

A take-up bobbin 65 is adjustably carried by the shuttle 13 slightly spaced from'the spindle 53 and is provided with opposite parallel guide pins 66 projecting therefrom and over which the tape or covering strip 11 is tensioned intermediate of its travel. The said bobbin 65 is mounted upon a central screw post 80 while a securing screw 81 car- 'ried by the shuttle projects through ami arcuate slot 82 in the said bobbin, it being evident that the bobbin may be turned and then retained in its adjusted position by means of the screw 81, thus changing the tension upon the strip 11 as may be found desirable. l

llt has been found in operation that the surface of the tire 12A upon which the covering is being wound or from which the same is being unwound helically must be positioned at substantially the center of the shuttle and bracket', or in other words, the cross-section of the tire at the'point of operation is concentric with the shuttle and bracket andthe drums 37 and-38 are designed for so supporting the said tire, 1 2 to be operated upon. For allowing the admission of the tire within the shuttle and bracket for seating upon the traveling drums 37 and bracket 15 and a hinged section 68 for the U shuttle 13. The bracket section 67 has its unhinged end provided with a tongue 69 adapted for reception within a groove 70 of ping of the pinion is permitted revolublyA 1 for the lock 7l and that a cut-away portion is provided at one side of the groove 70. The hinged section 68 of the shuttle v13 is provided with a swinging latch 76 having an angular portion 77 orpositioning within a notch 78 oi the adjacent portion of thevshuttle while a bifurcated spring-pressed catch 79 is carried by the latch 7 6 for normally maintaining the latch in its closed position with the shuttle Jforming a oo mplete annulus. It will thus be seen that 'the tire 12 may be readily removed from the machine by releasing the lock 71 and latch 76 and swinging open the shuttle section 68 and bracket section 67 in the manner best illustrated in Fig. 5 of the drawings, whereupon the tire 12 lmay be readily elevated and removed while a new tire may be quickly arranged to take its place in operative ,position upon the drums, and the shuttle and bracket sections then closed.

In operating lthe machine-for unwinding the covering strip 11, the tire 12 is placed in position as illustrated in the lirst four figures of the drawings and the strip 1'1 is adjusted over the guide pins 66 and its free end secured to the spool 61. Upon applying power to the shaft 31, the shuttle 13 is revolved in the direction indicated by the arrows which will carry the take-up bobbin 65 and the spindle 53 around and through the tire 12 upon the repeated revolutions of the shuttle. The meshing of the pinion 55 with the teeth 30 of the stationary bracket is such as to provide a greater rapidity of revolution of the pinion 55 than is necessary for winding the same upon the spool 61 so that the tensioning'of the strip 11 between the spool and the tire 12 and over the guide pins 66 is assured. The revolving of the l aft 31 alsorevolves mounting drums Bf'and' 38 finthe mannery hereinbefore del scribed,which:effects a :slow revolution of .5 portiffon'of thestrip 1'1 substantial y the sainejyjerti'cal pla-ne las the-takeup bobbin"65 and"spo'o l 61 at all time's during the unwinding operation of the device. The pedal 49 maybe employed whenever the speed of'ro- .10 tationofthe tire 12 is too great and .moves the unwinding vportion of `the tape out of the proper alinement s o that by means of the said pedal 49 the position'of-the tire 12 is regulated as desired'.

l i155,4 The completely vulcanized' tireihaving its envelop wrapping thereon may bethus posl- ,tionedv upon the present machine and the machine'iput in operation and thepwiapping` strip 11 completely unwound therefrom andreeled uponthe spool 61 and thespool removed from the spindle 53 byI depressing the spring fingers 63 so that the strip 11 may be again usedupon another tire. When desired to wrap the strip 11 helically around 525 a tire 12, the filled spool 61 is positioned upon the spindle 53 and the stripll fed over thevguide pin 66 and the free end ofthe -strip attached to the surface-of the tire112. The power shaft 31 is then revolved in a reverse direction and the strip 11 will be helically wrapped so as to completely envelop the tire 12 andthe strip 11-will b'e suitablymaintained under the proper tension for wrapping the same tightly around "35 the tire by means of the resilient mounting of the operating pinion 55 upon the spool spindle 53 as heretofore described. The device therefore fulils the objects for which it is intended and Will readily wrap or un- .40 Wrap a tireshoe, feeding the tire. shoe along simultaneously with the Wrapping or unwrapping operation. Elongated members y such as .cables ,may also bewrappedjornnwrapped" by the present device by longitudivnally-'and shiftably mounting the same in any desired manner substantially axially of theshuttle 13-aI1'd-b13fcket 15. --2 For` rendering the operation of the device more noiseless, it Will in some instances, be

y :found desirable'to substitute a friction drive connection. between the spoolv spindle 53 rand A thebracket 15, This varlaticn is' illustrated 'in'igl'lG `of the `drawing in which the brafcletflf is providedA with a leather or .-ot'he` 'form of facing strip 30 While the 'pini' '5 5"h'as av covering 75 in frictional contact therewith. The spool 61 is removably mounted' upon the spindle 53', which spindle is journaled through the'shuttle 13', '60 the wheel 55 having a resilient journaling cnnnection with'the spindle similar to the mountingfof' the pinion 53 hereinbefore 'def scribed.
